New on the Network Tools page: a Traceroute / Ping Visualizer. Paste raw output from traceroute, Windows tracert, or ping and it turns the wall of text into something you can actually read at a glance — a per-hop latency chain or a per-packet chart, with timeouts, latency jumps, and dropped packets flagged automatically.

What It Does

It auto-detects which of the four formats you pasted — Linux/Mac traceroute, Windows tracert, Linux ping, or Windows ping — and renders the right visualization:

MTU problems are some of the most annoying things to troubleshoot in networking, because they’re usually silent. Small packets sail through fine, everything looks healthy, and then someone complains that a specific app is slow or hanging — and it turns out one link in the path, three hops in, has an MTU 8 bytes smaller than everyone assumed. GRE, IPsec, PPPoE, a VPN overlay, a jumbo-frame config that only got applied to half the path, a VLAN tag quietly adding 4 bytes nobody accounted for, or just two vendors defining and displaying “MTU” differently (L2 vs. L3, tagged vs. untagged) — any of these can quietly clip your effective MTU, and standard ping/traceroute won’t tell you where.
